FEEDING DEVICE FOR ROLLING-MILLS.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed November 29, 1905. Serial No. 289.612.

To all whom it may concern:

Be it known that I, EDWIN E. SLroK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Feeding Device for Rolling-Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a lan view of a portion of the rolling-mill em odyin my invention, the rolluides and their ac juncts being removed for t e purpose of better showing the pinchrolls and their operating and lifting mechanism. Fi 2 is a front elevation showing the pinchrol s and their adjuncts in their receiving positions. Fig. 3 is a view similar to Fig. 2, but with the pinch-rolls raised into line with the edging-passes of the rolls; and Fig. 4 is a side elevation of the pinch-roll mechanism.

The invention has relation to rolling-mills such as are used for reducing ingots, blooms, slabs, &c., to a finished material, which require to be turned from a flat to an edgewise position before being passed through some of the passes in the reducing-rolls; and the invention is designed to provide improved means for turning and transferring such blanks from the position in which they are de livered from the rolls into position to enter a subsequent pass in the rolls and to provide means on the turning mechanism by which the blanks are held in their turned position and are positively fed into the rolls while being held in their turned position.

11 carrying out my invention I obtain the foregoing ob ect by mounting the housings for the pinch-rolls and the guides upon the machine in such a manner that they may move bodily from their horizontal receiving positions to a vertical position wherein the pinch-rolls are in line with one of a series of edging-passes in the reducing-rolls.

My invention also provides means whereby the pinch-rolls are opened or separated to receive the bar or other object at the time it is about to enter the same from the rolls and to subsequently close upon the bar, thereby preventing the end of said bar from flexing or uckling in entering.

In the drawings, 2 represents the reducingrolls, from which the bar passes to the guides 3 and pinch-rolls 4. The pinch-rolls 4 are j ournaled in the usual manner in the housings 5, carried by arms 7, which, together with the arms 7", which support the guides 3, are secured to a rock-shaft 6. The pinch-rolls 4 are driven by motor 8, which drives the shaft 9 through the gearing 8*. The shaft 9 carries a bevel gear-wheel 9, which meshes with a similar wheel 9' on the shaft 6, and which drives a third wheel 9 on the short shaft 9 The rock-shaft 6 is actuated bv means of the hydraulic cylinders 12 through the medium of the connecting rods or links 11, connected to the arm 13 of said shafts.

14 and 15 designate, respectively, the slabbing and edging passes of the reducing-rolls, which are journaled and driven in the usual manner. (Not shown.) The journal 16 of the upper pinch-roll is movable in the guides 17 of the housing 5 and is rovided with the usual housing-springs. T c said journal is connected by links 18 with stop-levers 19, pivoted at 20 and adapted to engage a stop 21.

The operation is as follows: The bar or other piece entering the guides 3 from the reducing-roll pass 14 and passing through the pinch-rolls 4 is liftedinto proper relation to the edging-passes 15 of the rolls by actuatin the rock-shaft 6 to raise the pinch-rolls an the said guide into the vertical position. (Shown in Fig. 3.) It will be seen that the arrangoment of the gearin above described for actuating the pinch-r0 ls will permit this movement of the said rolls and will also permit either movement to be reversed. As the pinch-rolls and guides are lowered to posi tion to receive a new bar the lever 19 engages the stop 21, and thereby raises the upper pinch-roll in the guide 17 sufficiently to spread the two rolls to receive another bar. As the inch-rolls are again lifted to the position s iown in Fig. 3 the upper roll is closed to pinch the bar. In this manner the entry of the bar to these rolls is greatly facilitated and its buckling or flexing is prevented.

It will be apparent that by using and operating the pinch-rolls in the manner above described I am enabled to positively feed fiat blanks forwardly into engagement with the reducing-rolls while they are held on edge.

Variations in the construction and the arrangement of the parts may be made without departing from my invention.
